In the study, aluminum plates were first anodized and then coated with ZnO by spray-pyrolysis method. By modification with long chain fatty acid, these surfaces demonstrate superior hydrophobicity and durability. After optimizing the anodizing time for each fatty acid, several runs were conducted by varying concentration and spray solution quantity. Comparison was made by optimizing the process parameters in which each acid showed maximum hydrophobicity. Anodized, spray coated and modified surfaces were characterized by FT-IR, XRD, SEM and topography analysis. The chemical and mechanical strength of the surfaces were explored under various extreme conditions. The highest contact angle of 164° was obtained by coating 10 minutes anodized surface with 0.4 M and 15 ml ZnNO₃ solution and modifying it with stearic acid. In the performed tests, it has been observed that this surface is much more durable than surfaces modified with other fatty acids.

在这项研究中，铝板首先进行阳极氧化，然后通过喷雾热解法涂敷氧化锌。通过用长链脂肪酸改性，这些表面表现出优异的疏水性和耐久性。在优化每种脂肪酸的阳极氧化时间后，通过改变浓度和喷雾溶液量进行了几次运行。通过优化其中每种酸显示最大疏水性的工艺参数进行比较。通过 FT-IR、XRD、SEM 和形貌分析对阳极氧化、喷涂和改性表面进行了表征。在各种极端条件下探索了表面的化学和机械强度。通过用 0.4 M 和 15 ml ZnNO ₃涂覆 10 分钟的阳极氧化表面获得 164° 的最高接触角溶液并用硬脂酸改性。在进行的测试中，已经观察到该表面比用其他脂肪酸改性的表面更耐用。
